Application filed April 28, 1914. Serial No. 834,888.

.Be it known that I, JOHN H. Benn, citi.

zen oft he United States, and resident of the borough of Manhattan, city of New York, in. the county of New. York and State of New York, have invented certain new and useful Improvements in Type-VVrrtmg Machines and more particularly to tabulating chines, of which thefollowing is a specification.

My invention relates to typewriting mamechanism therefor.

p The objects or the invention, generally I l stated, may be said to be as follows: (a) To provide a comparatively simple tabulating mechanism which occupies but little space,

. and the parts of which may be manufactured at small cost and readily assembled, and a;

e-rate and efiicient in use.

tabulator produced which is simple to op- (b) To provide .an improved tabulating mechanism in which --tabulatio'n may be readily effected.

backward or reverse as .well'as forward (0) To provide tabulating mechanism in which parts thereof may be .readily arranged to accommodate the mechanism to different 1 C l12LISLCl1BI'S of letter space feed of thecar- ,riage. (d) To provide a tabulating mechanism in which a disengagement between the stops may be more easily effected than heretofore, and in which therefore there is less liability of a tionally held in its projected position. (a)

ro'j ected stop being uninten- To provide a tabulator which enables access to be readily gained to different parts thereof and enables the parts to be readily dismounted, and replaced when desired.

, To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set -forth in the following specification and particula-rly pointed out in the appended claims.

Thus it will be seen that showing the clutch by which the carriage the clutch member-19 is provided with two rearwardly projecting fingers .21 on opposite may be releasedfrom control of the sides thereof. These fingers constitute escapement mechanism.

A clutch section 19 has a central opening,"- carriage 4 has oppositely grooved guide rails chamber or recess 27 therein and in which a ,5 which receive anti-frictionballs or rollers coiled expansion spring 28 is received. The 6, the latter also being received in oppositely forward end of the spring bears-against the grooved fixed guide rails7securedto the top. bottom wall of the recess 27 of the clutch plate of'the machine. The carriage supports member 19, whereas the rear end of the a cylindrical platen 8 against the front face spring bears against the hub 24 of the of which upwardly and rearwardly striking escapement wheel. The spring 28 thus tends type bars (not shown) are adapted to strike. to maintain the clutch member 19 in effective The carriage is thus mounted for movement engagement with its companion .clutch memi from side to side of the machine over the her 184:0 lock the escapement wheel and feed I The rear end of the shaft 15 is received in a the follo top plate under the power of a spring drum pinion' 'to turn together during a letter feed 9' connected with the carriage through a movement of the carriage and when a stepband 10. by-step fired movement of the escapement The movement of the carriage under the wheel" is "afforded by the usual feed dogs, power applied thereto by the spring drum-is not shown.

As hereinbefore explained the's'leeve '14, feedpini'on. 13 and clutch member 18 arefree to turn on the shaft 15 unless constrained to turn with the shaft through the engagement of the clutch members 18 and 19. The sleeve-14 is prevented from movinglongitudinally along the shaft 15 in one direction bythe engagef -1nent of the sleeve with the bracket member 16,whereas the rear end of the sleeve co-acts with'a circumferential shoulder 20 (see Fig.

23) on the shaft 15 to prevent a movement ofthe sleeve 14'longitudina1iy of the, shaft iuthe-op osite direction. The circumferen-' tialz'shou der 20 is formed atthe junction between the body portion of.the shaft 15 and it will be seen that these pins project in opposite directions from a release frame or device, designated as a whole by the reference numeral 31. The frame 31 is in the nature of two sheet metal bell crank levers united by an integral cross-bar 32'. Therelease. frame is" pivoted at 33 to the castin 16 and in its pivotal movement is adapted to throw the clutch member 19 rearwardly and disengage it from the clutch member 18.

I have provided hand actuated carriage 6 releasing means cooperative with the release frame 31 as well as automatically operating means controlled bythe tabulator to operate said frameand the clutch controlledthere by. The hand actuated carriage releaseis shown in Figs; 2 and 20 from which it will be understood that levers 34 are pivoted at "35 'to the'end plates of the carriage and are united at theirrear ends by an angle ha'r'36- I which extends throughout the length of the iage. fi e 6f the" lerers is extended:

Itwill be an c all of the spacingplates 63 are of like contour but of. diiferent thicknesses, except the center interlocking plate of the thicker series of sp cing plates. One of these last mentioned plates is shown in detail in Figs. 21 and 22 from which it will be seen that the portions 67 and 68 which engage in the notches and 66, respectively, are thinner than the body portions of the plates and are formedby reducing the metal at the engag ing portions as, for example, by millin cuts. The notches 65 and 66 are eachiof awi th to correspond to the thickness of the thinner spacing plate, but by reducing the thickness of the thicker center spacing plate at those portions thereof which engage in said notches, the same notches may be employed for center plates of different thicknesses. By thus providing interchangleable spacing plates interposed between t e denominato accord with the. spacing or letter feed of the carriage, it merely being'necessary to substitute spacin plates of one thickness for s acing plates 0 a diil'erent The enommational stops, it will "be understood,

Each of these actuating members has an elongated body portion 4 which extends in the general direction of the travel of'the carriage and has projecting. from its body rtion widely separated crank arms 75 an 76 which extend at right angles to each other and at right angles to the body portion of the actuating member. of the actuating members has its bearing points 72 at one edge ofthe body portion 74 arranged to be seated in a pair of bearin slpacing plate 69.

means':- Each of the denominational stops member 110 atthe rear endithereof. Each operate vwith a'universal release bar 111 which is preferably formed of sheet metal and constitutes a part of a yoke-like mam; her including parallel arms 112, 113. These arms are pivoted at 114 to depending arms 115 .of a sheet metal bracket having across bar 116 which unites the bracket arms 115. This bracket is riveted. asvat 117 (Fig. 8)

to the body portionof the ,tabulator housing. s The arm 112 of the release member'is extended downwardly beyond ,its pivot (see Fig. 5) to provide an arm 118 pivotally connected at119 to-a sheet metal releasing memneath the tabulator housing and is provided with a hook-like engagingportion 121 at the forwa'rd'end thereof. A sheet metal bracket-120 is fixed to the housing and is formed with a hook-like bearing portion at the lower end thereofto receive and guide the forward end of the link 120 in its fore and aft movement,. and to cause the link to be shifted bodily with the housing in the bodily movementof the latter, as will hereinafter more clearly appear. As indicated in Figs. 2 and 10, the hook-like engaging end of this releasing link 120 is arranged to cooperate with the pin 41 on thereleasing frame 31. A contractilespring 122 is connected at one end to the arm 118 of the universal bar frame-and at its other end to apin 123 (see Fig. 1) which is connected to and extends downwardly fromthebottom of the'tabulator housing.- This spring is effective to return the universal release bar 111 and the partsconnected therewith to normal position.

This movement of the releasing link is effective to turn the releasing 76 7 frame 31 on its pivots, thus moving the clutch section 19 rearwardly to release the carriage from the control of its escapeinent mechanism, as hereinbefore explained. 1 When pressure on the actuated tabulator key is released the associated springs 100, 122, 41'- and 28 will return the parts to normal position, the carriage in the meantime havmg been arrested by the cooperation of the rejected denominational stop with one of the'column stops 46.

It will be understood from the foregoing description that an actuation of a tabulator key'ii's operative to project the associated denominational stop and to release the car- 9 riage andenable it to travel under the power" of the spring drum in the direction of its" feed until arrested by the cooperation of the projected denominational stop with the first of the column stops' lti. However, I' have provided meanswhereby a backward or reverse tabulation 'may be effected when desired, and by"whiehQthe carriage may be arrested at the same denominational or letter space position whether the-carriage 9 be arrested under a forward or abackward tabulation.

One of the advantages of making the members 133- and 138'in two, pieces and de tachablyfconnecting them, instead of makthem as one casting or piece as in the prev ously described constructiomis that a remoyal of the screws 137 enables the tabu lator housing'and the parts carried thereby to 'be detached and a diflerent charactor of to ulating mechanism, such as a column selecto'r, to be substituted therefor. The body portion of the housing 126 is also formed with a bracket or car 148 by means .ofwhich one end of a-contr'actile spring 149 .maybe connected to the h I. using.

l1 i i-Oman inspection offFig. 12 it will be observed that Ia. contractile sprin 160 is connected at one end tome depen ingarm 157 ofthe universalrelease bar and is-connected, at its'io pposite end to the ear 148 on the body portion of-the housing. The power of this sprin 160 is exerted .to return the uni,

verse. release, barand the parts connected therewith to normal-position. The releasing member 158 is in the nature of a wire provided with a bend .161 which forms a crank ',arm, as 'clea'rlyr shown in Fig. 16.

leasing member is adapted to bear against the lower edge pf a depending arm 163 of a sheet metal bracket, desi by the reference numera 164, as clearly shown inf Fi'g. 16. This'bracket is to the front of the body portion -of the'tabu- 'ated as a whole lator housing and. is provided with-,a'forwardly extending arm 165'towhich one end-- of a contractile spring 166 isbonnected, the

opposite end of this spring be'] connected to the crank arm 161 to normagainst the lower bracket 164 is a soprovided with a depending arm or iear 167 hpertured; to receive y maintain a the forward end portion of. the releasing member 158,150 thatsaidh ember isfree to move longitudinally in the bearin opening of the arm 16'} and also to turn;t erein as" will hereinafter more clearly appear. The

pivotal connection between the memberf158 an the universal releasing bar. is 'such,-ajs

will be understood from m inspeetionvof i Fig. 11, as to afford a 'slightrotative move ment of the member 158. When the uni- '-versal release bar is actuated by one of the denominational stops. 62, -a. longitu'dinal u movement of the member 158 will be. efiectod to actuate'the rcleasin frame 31 through an engagement of the pm 41. thereon. Dur- 'ing this fore-and aft movement of the re leasing member 158 thefcrank arm 161 '00- -acts'with the part 163 to 'prevent the memher 158 from bein turned on its longitw dinal axis under t 0 power of the spring 166.

During a backward tabulation the member-158has a bodily movement with the housing to the right, as in the previously deseribediconstruction. The .gfectof this f is to carry the enga mem r1 2 away gli ge'ase .the latter and enable thecarriag'e to be automatically re-,

from the pin 41 an stored to the control of its-escapement mechanism. If the, carriage should be quickly released by the hand of the; o rator, before the carriage has been resto' viott- 119;; to the control of the escapement mechanism, and an acci- E dental engagementshould be efi'ected: be:

tween the engaging portion 162 of the "re leasin member 158 and the end of the in 41, this would result in turning the mem r 158 against the power of the spring 166 .so

as to prevent a blocking engagement be-' tween the parts 41' and 162 which might prevent a returnmovement of the in41 to normal position, andthus, throug frictional resistance, prevent a restoration of the carriage .to the control of its escapement mechanism. The pivotal movement of the member 158 thus effected is operative to.

move the crank arm 161 away from the abutq ment 163. but as soon as the. pin 41 is restored tonormal position, through the rengiige ment'of the clutch-members. 18-and 19.,the power of the 166 eii'ective turn the member 158 and bring the crank arm 161 against the abutment 163, thus restoring the member 158 to its normal position, riot'atively considered. This pivotal movementof the member 158' and the means by which such pivotal movement .is effected constitute in eflect safety means for preventing a premature rengagement between the part 162Yand the pin 41 from blocking the parts'and thereby preventing an automatic restoration of the carriage to the control of its escapement mechanism,

In the construction shown in Figs. 11 to 17, inclusive, the spacing plate 168 is similar to 15 construction -except that the bearing .aper

that: employed in the previously described tures or openings 169 thereinjar'e of different formation and are differently disposed in the plate. In'this preferred'form'of construction. the apertures 169 arepunched out and are preferably in the nature of oblong slots which, asin the previously described construction, receive. the bearingprojections on actuating' members 73*. members are similar to those employed in the previously described construction,- and .illustratedin detail in Fig. 9, except for slight changes in detail.- For example, the -forwardvend's of the actuating arms 76 are bent laterally as at."('6 to provide a better clearance between the arms atthe forward.

ends thereof and between the upper ends of the pull links 80twhich'are connected therewith. The upwardly. extending arm- 75 of each actuating member 73 isconnected. with a denominationalstop'in the same manner -a-s in -th previously described construction.

' It will beseen, however, that the pivotal axis of'each of these actuating member's, instead of extending'at right anglesto a vertically M disposedplane' extending fore and aft of the f mach ine, is arranged at anoblique angle to said'plane, and that" the bearing apertures- 169 have a corresponding arrangemental though, as in the previously described com struction, they have an echelon' arrangement.

. 1 mounting the actuating. devices 73? in themanner described they'are adaptedto cooperate with the denominational stops 62" which, as. shownin Fig. 11, are in parallel vertical planes arranged at-anangle to a" vertical plane extending fore and aft of the machine. The plane of movement, there fore, of each of; the denominational stops is at an'obliqueangle to-the plane of each of tlie t will beunderstood that'by this arrangement each denominational'stop,as it moves rearwardly out of engagementwith a column stop,' also'-moves slightly to the left or in the general direction ofthefeed of the carriage.

- It vwill be seen, therefore, that a disengagemerit-' between a= projected denominational stop and a columnsto p cajn be more easily These actuating effected than in an ordinary construction in which the disengaging movement'is in a fore and aft vertical plane, or ina direction'at right angles to'the line of travel of the carriage. By reason of this disengagement of the denominational stop by a movement slightlyto the left as well-as to the rear, there -isbut little tendency for the power of the carriage, exerted through the engaged column stop, to prevent the projected andengageddenominationaI stop from being restored to normal. position, even though a comparatively light spring be employed to return the denominational key and the-stop controlled thereby to their normal positions.

In the form of construction shown in Figs.

11 to'l7- inclusive, detachable spacing plates .63, similar to-those. previously described, are employed exceptthat they have ail-angular disposition corresponding-t0 the angular disposition of the denominational stops. Moreover, the tabulator frame is notched at as in the previously described construction,

spacing plate. Furthermore, the cover plate 145., is notched in a like manner for -co-' operation with the centrally disposedspacing plate. The plate 168, shown in detail in Fig. 14, is similar to that shown in Fig. 11.

except that the apertures 169 in the two the plates 168' is effective to produce a corresponding spacing of said actuating members, so that the upright arms thereof will properly-co-act with-the denominational .stops when the latter are spaced apart according to the spacing plate 168 employed in 'the machine.

The operation of the mechanism illustrated-in Figs. 11 to 17 inc1usive, will*be understood, it is believed, from the foregoing description, the operation, generally speak- 'ing, being similar to the constructiondisfor interlocking engagement with the center closed in the preceding figures, except for 4 the withdrawal ofthe denominational stops rearwardly and in the direction of letter feed movement of the carriage, and except for the operation under certain conditions of .the releasing member. 158against the power of the spring 166 to prevent a blocking of the means by which an automatic'restoration of the carriage to the control-of the escapement mechanism is effected.
